The malicious call identification (MCID) feature allows a user to report a call of a malicious nature by requesting that Cisco Unified Communications Manager identify and register the source of an incoming call in the network.

Malicious call identification (MCID), an internetwork service, allows users to initiate a sequence of events when they receive calls with a malicious intent. The user who receives a disturbing call can invoke the MCID feature by using a softkey or feature button while the user is connected to the call. The MCID service immediately flags the call as a malicious call with an alarm notification to the Cisco Unified Communications Manager administrator. The MCID service flags the call detail record (CDR) with the MCID notice and sends a notification to the off-net PSTN that a malicious call is in progress.
